Used primarily as an intermediate in the synthesis of heterocyclic compounds, particularly in the production of thiadiazole and triazole derivatives which exhibit biological activity. It serves in agrochemical manufacturing, including certain herbicides and fungicides. Also employed in the development of pharmaceuticals, especially in creating compounds with antimicrobial, antifungal, and antiviral properties. Its reactivity makes it valuable in coordination chemistry for forming metal complexes with catalytic or material applications.
